authenticate: use gRPC for service endpoints (#39)
* authenticate: set cookie secure as default.
* authenticate: remove single flight provider.
* authenticate/providers: Rename “ProviderData” to “IdentityProvider”
* authenticate/providers: Fixed an issue where scopes were not being overwritten
* proxy/authenticate : http client code removed.
* proxy: standardized session variable names between services.
* docs: change basic docker-config to be an “all-in-one” example with no nginx load.
* docs:  nginx balanced docker compose example with intra-ingress settings.
* license:  attribution for adaptation of goji’s middleware pattern.
